Taylor and Jake haven't been photographed together since December 9 in Los Angeles, after photogs caught them on cutesy coffee dates and doing their shopping together.

But Taylor Swift and Jake Gyllenhaal spent the holidays -- and their birthdays -- separately. Taylor partied the New Year away in Nashville solo while Jake was in New York attending a closing party for the Broadway musical Fela! and noshing with his mom.

So what happened?

Did they finally recognize the huge gap in maturity between a 21-year-old and a 30-year-old? Was Chris Hansen waiting for Jake in Taylor's kitchen? Did their publicists realize that their fake romance wasn't taking the public by storm?

Their reps aren't talking, but don't look for these two holding hands and skipping down the street on the cover of Us Magazine any time soon. Taylor will spill all the dirty details on her next album.
